Abstract: A laser printing system includes a laser configured to produce a beam of light modulated according to image data input to the laser printing system, a photoreceptor drum including a photoconductive layer disposed along an outer peripheral surface of the photoreceptor drum, and a non-mechanical beam steerer configured for receiving the modulated light beam from the laser and steering the light beam in a scanning motion back and forth across the photoconductive layer of the photoreceptor drum. The laser printing system also includes a printer controller configured to structure the image data input to the laser printing system, and control an amount of electrical current flowing through portions of the non-mechanical beam steerer to change an effective index of refraction of the non-mechanical beam steerer and steer the modulated light beam in the scanning motion.

Abstract: A display system for providing a two dimensional image includes an essentially one dimensional light valve array. The diffractive light valve array includes modulator elements which diffract or reflect light incident thereon to an extent determined by an image element to be represented. The display system is arranged such diffracted light from the light-valve array passes through a magnifying lens and is separated from the reflected light from the array. A magnified virtual image of the array formed by the diffracted light is viewed through the magnifying lens. A scanning arrangement between the viewer and the magnifying lens scans the image of the light-valve array across the field of view of the viewer sufficiently quickly that the viewer perceives the scanned image as a two-dimensional image. In another arrangement a printer is formed by scanning a real image of the diffractive light valve array over a printing or recording medium.

Abstract: A digital micromirror device is provided with micromirrors disposed in matrix form. Each micromirror is changed between a valid reflection state and an invalid reflection state according to mirror drive data. In the valid reflection state, reflected spot light is guided to an image forming optical path and a photographic paper is exposed. In the invalid reflection state, reflected spot light is guided to an eliminating optical path. A photodetector performing a photometry of the spot light is disposed at the eliminating optical path. The micromirrors are set in the invalid reflection state one by one and the reflected spot light is measured by the photodetector so as to examine the existence of a faulty micromirror or scatter of reflectance of the micromirror. All micromirrors are set in the invalid reflection state at the same time and an output of the photodetector is inspected so as to examine whether light amount of a light source is proper or improper.

Abstract: A fluorescent dyed polymer member and a light source are structurally arranged in a manner to efficiently gather light from the light source and then transmit the gathered light to a light utilization device. Light from the light source is gathered over a large area that is occupied by the polymer member. This gathered light is transmitted through the polymer member to an edge portion thereof having a relatively small light emitting area. Light is then emitted as an external beam having a cross section that corresponds to the physical shape of the edge of the polymer member, for example a straight of linear footprint of light. The area brightness of this external beam is greater than the area brightness of the initial light source.

Abstract: An electronic printer, comprising a fiber optic bundle having the fiber ends organized in a linear array in a first face and in an area array in a second face, includes a linear array of LEDs or LCSs adapted to image light into the fiber ends in one linear segment of the area face at a time. A rotating mirror is operative to move the light image onto each of the consecutive linear segments on the area face and to provide a digital signal indicative of the position of the light image in each instance. The arrangement provides a low cost, high speed, and small size electronic printer which is easily adapted to high resolution and color printing.

Abstract: The invention relates to a liquid crystal optical switch array in which optical switch elements are opened and closed by the time-sharing drive and to an optical printer using this optical switch array. The optical switch element comprises a ferroelectric liquid crystal having a relaxative memory effect, signal electrodes and scanning electrodes which sandwich the liquid crystal layer, and a resistor element which is formed between the scanning electrode and the liquid crystal. A line selection signal is sequentially supplied to the scanning electrodes, these scanning electrodes become substantially the open state when the selection signal is not supplied. When the scanning electrodes are open, the resistor element has a predetermined resistance value. When the selection signal is supplied to the scanning electrodes, the resistor element has a lower resistance value.
